There are about 5012 clinical studies being (or have been) conducted in Mexico. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The goal of this clinical trial es to learn about the short term effects of intravitreal dexamethasone implant (IDI) in patients with refractory diabetic macular edema. The main question it aims to answer is: How fast does the diminishing in central retinal thickness has statistical significance after IDI in patients with refractory diabetic macular edema? Patients will be evaluated by OCT before and after the implant.
The objective of this study was to compare the short- and medium-term effects in pain and temporomandibular joint (TMJ) and function of implementing a manual therapy (MT) intervention treatment combined with a therapeutic exercise (TE) program, versus an isolated TE program and a non-intervention in patients with disc displacement with reduction (DDCR) with pain.
Type 2 Diabetes Mellitus (T2DM) is a group of metabolic disorders characterized by hyperglycemia in the absence of treatment, positioned in the first places of prevalence and mortality in the Mexican population. Adherence to treatment is a central element to prevent complications of the disease, where the active participation of the patient in his or her treatment is fundamental. Despite institutional healthcare efforts to promote this element, there is no clarity in the Clinical Practice Guidelines aimed at the attention of people with T2DM on how to achieve it. The aim of this project will be to evaluate the effect of an intervention based on Contingency Behavior Analysis on treatment adherence, quality of life and glycemic level in people with newly diagnosed T2DM. Pre-experimental design with pretest and posttest measurements. The Dependent Variable will be an intervention based on Contingency Behavior Analysis. The Independent Variables will be adherence to treatment, quality of life and glycemic level. The power calculation suggests an n = 38, using sequential non-probability sampling. People older than 18 years with less than 5 years of T2DM diagnosis will be included. Pretest and posttest differences, effect size and correlations between measurement variables will be analyzed. It is expected that the intervention based on Contingency Behavior Analysis will encourage the active participation of people with T2DM, improving their adherence to treatment, glycemic level and quality of life. Considering that the Clinical Practice Guidelines emphasize the importance of therapeutic adherence through the active participation of the patient and his/her environment, it is expected that this project will provide the tools for behavioral change that so far are not included in public health in Mexico.
The flexion of the mandible (MF) is a multifactorial phenomenon that occurs simultaneously with mandibular movements determining changes in the shape of the mandible. mandibular flexure (MF) may cause complications and failures in both conventional and implant-supported fixed dental prostheses (FDP) especially when a long-span prosthesis is planned to connect the anterior to the posterior region of the mandible. Previous studies reported increased biomechanical stress at the prosthetic and implant level, poor passivity of fit, impression distortion, pain during function, de-cementation of the prosthesis, porcelain chipping, prosthetic screw loosening and fracture, bone resorption and implant fracture. The aim of this study is to quantify the dimensional changes related to MF by means of a cone beam computed tomography (CBCT) between maximum opening (MO) and maximum intercuspation (OVD) positions. The null hypothesis was that there is no significant difference in terms of length and width of the mandible between maximum intercuspation and maximum opening positions.
This is a phase II/III parallel, double-blind, active-controlled, non-inferiority study to evaluate immunogenicity and safety of a booster immunization scheme of a single intramuscular dose of the recombinant vaccine against SARS-CoV-2 (AVX/COVID-12 vaccine) based on live recombinant Newcastle disease virus (rNDV) vector in healthy adults with a history of vaccination against COVID-19. The study is divided into two phases with immuno-bridging and 3000 healthy subjects showing evidence of prior immunity to SARS-CoV-2 are estimated to enrol. To verify non-inferiority in a determined number of subjects an intramuscular dose of the COVID-19 vaccine (ChAdOx-1-S[recombinant]) shall be used as active control in originally randomised subjects. The study shall be carried out in several sites of clinical research in Mexico.
Study design: Randomized control trial Purpose: Evaluate the efficacy of oral administration of tranexamic acid (TXA) in spine surgeries to achieve blood loss reduction. Methods. A total of 60 patients undergoing major surgery of the spine, were randomly assigned into 2 groups. Group 1 was assigned as the control group and the other one included oral administration of tranexamic acid 2 hours prior to surgery. Outcomes measures included intraoperative blood loss, postoperative blood loss, hematological parameters, blood transfusion needed, and surgical complications.
Therapeutic exercise is one of the therapies used as a treatment for diabetic neuropathy, which is a complication of diabetes. In order to reduce pain and improve the perception of quality of life, a combined therapeutic exercise program will be implemented as an adjuvant and non-pharmacological treatment for diabetic neuropathy.
The treatment of melasma and the maintenance of depigmentation represent a challenge due to its frequent recurrences. Pathophysiological mechanisms and factors have been linked to melasma such as inflammation, sun exposure, increased CD4+ T lymphocytic infiltrate and IL-17 in damaged skin. Tissue-resident memory T cells (Trm), derived from naïve T lymphocytes, are associated with the recurrence of lesions at the same sites but they have not been described in melasma. This a Cross-sectional, prospective analytical study. 20 female patients, 18 to 55 years of age, with diagnosis of melasma and mMASI score of at least 7, at least 1-year duration, lesional and perilesional skin biopsies were taken for PCR and DIF. The objective is to determine the transcription factors of Trm cells in malar melasma.
The study objective was to compare short-term clinical performance data of two toric contact lenses.
This study is aimed to evaluate the bioavailability of methylprednisolone in healthy subjects of both genders, with administration intranasally versus intravenous
